They have been, literally, defenseless for six games, yielding an average of 107.2 points, and have been particularly brutal for the last three, which has been their worst field-goal-defense stretch in almost a year.

It’s no coincidence the losing streak going against the Lakers tomorrow is six with the last three defeats coming by 53 points. At least the Nets have been drama-free at the end of games, and it might continue. The Lakers have the NBA’s third-highest scoring offense.

“We’re kind of changing a couple [of] things here and there so we’re not reading situations well,” said Devin Harris, who suffered a sprained left shoulder Thursday in Dallas and is listed as “questionable” for L.A. — as is Derrick Favors (right thigh bruise).

Harris said the Nets wanted to run some different defensive schemes against the Mavericks but had trouble executing.

“[We had] some confusion on certain plays on what we’re doing, and it’s leaving us vulnerable on the weak side,” he said. “And we’re paying for it.”

In the past three games (Celtics, Hawks and Mavericks), all double-digit defeats, the Nets have allowed opponents to shoot .552 (127-of-230) from the field. That is the worst three-game stretch since a .554 run (129-of-233) in road losses to the jackrabbit Jazz, Warriors and Suns last Jan. 20-23. The Nets have dropped to 15th in the league in points allowed (they were top 10 all season).

“It’s been transition for the most part,” said Brook Lopez, awaiting the wrath of coach Avery Johnson. “Some is shot selection and getting back to get whatever man’s back as opposed to our own man.

“It’s something we have to figure out. I’m sure Avery will let us know. In film. On the court. One of those ways.”

Harris also gave the Nets’ opponents some credit.

“We’re playing against teams that are shooting hot right now: Boston, shooting hot; the Mavs are going well,” he said. “So part of it is how teams are shooting too.”

League sources say Denver seeks “closure” to the Carmelo Anthony saga and could trade the star forward earlier than the February deadline.

The Nets have no official offer on the table but remain confidently in the hunt for the star, proceeding as if Anthony would be amenable to a move to New Jersey.

Nets owner Mikhail Prokhorov retaliated in the playful war of words with Mavericks owner Mark Cuban, who admitted calling the Russian billionaire a vulgarity.
